Problem 1: Car Showroom

> In a car showroom there are 247 white cars and 343 red cars. How many cars are there in the showroom?

Step 1: Write down the numbers:

- Number of white cars → 247
- Number of red cars → 343

We add them together:

```
H T O
2 4 7
+ 3 4 3
-----------
5 9 0
```

Explanation:
- Ones: 7 + 3 = 10 → write 0, carry over 1
- Tens: 4 + 4 = 8, plus carry-over 1 = 9
- Hundreds: 2 + 3 = 5

So, total number of cars = 590

✔ Answer: 590 cars

Problem 2: Students in School Sections

> Section-A has 216 students and Section-B has 186 students. How many students are there in all?

Step 1: Write the numbers:

- Number of students in Section-A → 216
- Number of students in Section-B → 186

Add them:

```
H T O
2 1 6
+ 1 8 6
-----------
3 0 2
```

Explanation:
- Ones: 6 + 6 = 12 → write 2, carry over 1
- Tens: 1 + 8 = 9, plus carry-over 1 = 10 → write 0, carry over 1
- Hundreds: 2 + 1 = 3, plus carry-over 1 = 4

Wait! Let’s double-check:

- Hundreds: 2 + 1 = 3, plus carry-over from tens = 1 → 3 + 1 = 4

So correct sum is:

```
H T O
2 1 6
+ 1 8 6
-----------
4 0 2
```

✔ Answer: 402 students

Add:

```
H T O
1 5 6
+ 1 3 2
-----------
2 8 8
```

Explanation:
- Ones: 6 + 2 = 8
- Tens: 5 + 3 = 8

+ 1 6 4
-----------
3 3 8
```

Explanation:
- Ones: 4 + 4 = 8
- Tens: 7 + 6 = 13 → write 3, carry over 1
- Hundreds: 1 + 1 = 2, plus carry-over 1 = 3

✔ Answer: 338 flats
